 This example demonstrates creating a workflow-backed agent that runs autonomously in the background. The `AgentRunner` schedules the workflow for you, waits for completion, and ensures the agent can be triggered once yet continue execution across restarts.

 The snippets below reuse this `travel_planner` instance to illustrate each mode.
 
 #### 1. Ad-hoc execution with `runner.run(...)`
 
-Use `run` when you want to trigger a durable workflow directly from Python code (tests, CLIs, notebooks, etc.). The runner locates the agent's `@workflow_entry`, schedules it, and optionally waits for completion. Call `travel_planner.start()` first so the workflow runtime is registered.
